Screen resolutions also have base names, such as HDTV and UHD for TVs and XGA and WQXGA for computer monitors. However, the names are confusing. For example, "Q" can mean "quarter" or "quad." QVGA means one quarter the pixels in VGA, while QXGA means quad (four) times the resolution in XGA. Each of the following resolutions is also an entry in this encyclopedia.
